Description

Mechanical lock core that pellet shot from a slingshot is concealed and key

Affiliated technical field

The utility model relates to a kind of mechanical lock, is a kind of mechanical lock of hiding cylinder type.

Background technology

At present, the lock core of known mechanical lock is to be made of pellet shot from a slingshot in lock core key gathering sill and the groove, and after key inserted, the pellet shot from a slingshot position was controlled by teeth groove on the key, after the key, can open lock.Therefore existing mechanical lock can be stirred the pellet shot from a slingshot position and open lock because pellet shot from a slingshot exposes by master key, and existing mechanical locks that tool must theftproof performance.

For the pellet shot from a slingshot that overcomes existing machinery lock exposes, and opened the deficiency of lock by master key, the utility model provides a kind of pellet shot from a slingshot concealed mechanical lock.The concealed mechanical lock of this pellet shot from a slingshot can't insert in the key in the lock core master key, makes master key can't contact the pellet shot from a slingshot of mechanical lock with all unlocking tools and can not unblank.

The scheme that its technical problem that solves the utility model adopts is: in existing lock core.Add top board, a top board and have key insertion mouth, the circular hole gathering sill that key insertion mouth and top board are opened communicates, and the circular hole gathering sill is positioned at top board circle center.Have fan-shaped internal chute structure in the top board, after key inserts key socket and circular hole gathering sill, in fan-shaped internal chute, rotate to an angle after, continue again to insert in the lock core key chute.The pellet shot from a slingshot position of key control mechanical lock.After key turns, just can open this lock.

The beneficial effects of the utility model are: prevent that master key and all unlocking tools from opening the concealed mechanical lock of this pellet shot from a slingshot, this lockset has reliable anti-theft feature.
